Node Investment, for Drop Rate

[Tsel13]

Is the Node Investment to increase Drop Rate worth it?

Item Drop Rate from Energy Investment of Nodes:
* Item Drop Rate increases by 0.5% x the investment level.
* Item Drop Rate increases to 5% at Lv.10.
* Item Drop Rate increases to 10% at Lv.20.

What am I missing?
5% really doesn't seem like much of a gain.

Depends if you are using your energy or not :) IF you are using all your energy each day then No I wouldn't invest until you have a surplus of energy each day :) I have 599 energy and lots of characters so I can dump 12000-15000 energy in one go really easy, so used it to invest in all the main grind regions nodes and it does make a difference but it's nothing to write home about so to speak lol

My biggest issue with investing energy is worker nodes lol
does it make a difference to a worker mining a node for instance? or does the additional drop rate from the node get added to the region drop rate from the main region nodes or parent node?

To sum up Yes if you have energy going to waste No if you don't :)
